Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a household pressure cooker with a pressure visualization indicator. Background Technology
[0002] Household pressure cookers are a common kitchen appliance widely used in daily life. Their core working logic involves creating a sealed cooking space through a closed structure. During heating, the steam generated by water evaporation inside the pot cannot escape, creating a high-pressure environment. This raises the boiling point of the water inside the pot, creating high-temperature cooking conditions far exceeding normal pressure, thus achieving rapid simmering and tenderizing of ingredients, efficiently completing the cooking of various foods.
[0003] Currently, during heating, pressure holding, and pressure release, the high-pressure gas inside the pot is exhausted from the outlet. The high-pressure gas flow tends to spread irregularly in all directions, and the exhaust steam temperature is extremely high. If operators get close, they are very likely to be burned by the high-temperature steam, posing a significant safety risk.
[0004] Meanwhile, the handles on the side walls of most household pressure cookers are short and of unreasonable length. When users move the pot, their hands are too close to the hot pot, making it easy to accidentally touch the heated surface and cause burns. This makes them inconvenient to use. Furthermore, the lid and pot body fastening structure lacks anti-loosening limits during movement. When the pot shakes, the lid is prone to shifting or even slipping off, which can cause hot food to leak out and further increase the risk of burns. Overall, the safety and reliability of the pressure cooker need to be improved. Therefore, there is an urgent need to develop a household pressure cooker with a pressure visualization indicator. Utility Model Content
[0005] Purpose of the utility model: The purpose of this utility model is to provide a solution to the significant safety risk of high-pressure gas in the pot spreading irregularly when it is discharged from the outlet during the heating, pressure holding, and pressure release stages, which can easily cause burns to operators due to high-temperature steam.
[0006] Another objective of this utility model is to address the problem that the short handle on the side wall of the pot is poorly designed, resulting in the user's hand being too close to the hot pot body when moving it, easily causing accidental burns from touching the heated surface, and also compromising convenience. Simultaneously, it addresses the issue that the lid-pot body fastening structure lacks anti-loosening limits when the pot is moved, causing the lid to easily slip and fall, leading to leakage of hot food and secondary burns. This improves the safety and ease of operation of household pressure cookers, ensures reliability, and meets the safety needs of daily family cooking.
[0007] Technical Solution: A household pressure cooker with a pressure visualization indicator includes a pot body. A locking ring is fixedly installed on the upper surface of the pot body. Multiple L-shaped slots are formed on the upper surface of the locking ring. A lid is provided on the upper surface of the locking ring. Multiple L-shaped blocks are fixedly installed on the lower surface of the lid. The L-shaped blocks engage with the L-shaped slots. A through-type vent groove is formed on the upper surface of the lid. L-shaped slots are located on both sides of the vent groove on the upper surface of the lid. A water collection box is provided on the upper surface of the lid. L-shaped blocks are fixedly installed on the lower surface of the water collection box. The L-shaped blocks engage with the L-shaped slots. The interior of the vent groove is fixed... A filter screen is installed. An air hood is fixedly installed on the upper surface of the air outlet slot. A pressure plug is slidably installed inside the air hood. A touch plate is fixedly installed on the upper surface of the pressure plug. Multiple mounting ring blocks are fixedly installed on the upper surface of the water collection box. A condensation plate is fixedly installed inside the mounting ring blocks. A rotating column is rotatably installed between two adjacent mounting ring blocks via a rotating shaft. A shaped striking block is fixed to the outer wall of the rotating column. The lower end of the shaped striking block is located inside the air hood and above the touch plate. The upper end of the shaped striking block is located above the condensation plate. A spring is fixedly installed on the shaped striking block and the mounting ring blocks, located on the outer wall of the rotating column.
[0008] Furthermore, handle boxes are fixedly installed on both sides of the pot body, and sliding grooves are opened on both sides of the inside of the handle boxes, with sliders slidably installed inside the two sliding grooves.
[0009] Furthermore, an extension plate is fixedly mounted on the opposite sides of the two sliders.
[0010] Furthermore, the extension plate has an internal long groove, a stop block is slidably installed inside the long groove, and a spring is fixedly installed between the long groove and the stop block.
[0011] Furthermore, both sides of the locking ring are provided with abutment grooves, which are connected to the L-shaped slot.
[0012] Furthermore, a second spring is fixedly installed inside the L-shaped slot, and a spring block is fixedly installed at the rear end of the second spring, with the spring block in contact with the L-shaped slot.
[0013] Furthermore, an operation screen is provided on the front surface of the pot body.
[0014] Furthermore, a handle is fixedly installed on the upper surface of the cover.
[0015] Beneficial effects: The high-pressure gas is filtered and diverted through the filter screen, and the air outlet hood restricts the airflow to be discharged in a directional manner to prevent it from scattering; the high-temperature steam is cooled and discharged as cold air through the condenser plate, which effectively prevents scalding; the condensed water droplets are collected in the water collection box and do not drip; the rise in air pressure triggers the knocking block to repeatedly knock the condenser plate, shaking off the water droplets to prevent blockage and ensuring smooth pressure relief.
[0016] The vent slot on the cover is equipped with a filter screen, which can filter and divert the discharged high-pressure gas to avoid airflow turbulence. The vent hood above the vent slot can directionally constrain the high-pressure airflow during heating, pressure holding, and pressure relief, preventing the airflow from spreading irregularly in all directions. The discharged high-temperature steam enters the water collection box that is engaged with the cover through the L-shaped slot 2. It is quickly cooled by the condenser plate on the mounting ring block, turning the hot gas into cold gas before being discharged, effectively preventing the operator from being scalded by high-temperature steam. At the same time, the water droplets produced after condensation are directly collected in the water collection box, preventing water droplets from dripping randomly. When the gas pressure inside the pot increases, it will push the pressure plug in the vent hood to move upward, causing the touch plate to hit the lower end of the irregular knocking block, making the irregular knocking block rotate around the rotating column. Its upper end hits the condenser plate simultaneously. With the reset action of the spring on the outside of the rotating column, the reciprocating knocking is achieved, which can shake off the water droplets attached to the surface of the condenser plate in time, solving the problem of water droplets clogging the air holes of the condenser plate after long-term use, ensuring that the pressure relief channel is unobstructed, and avoiding the safety hazard of abnormal pressure increase inside the pot.
[0017] The locking ring on the upper surface of the pot body is connected to the lid by an L-shaped slot and an L-shaped block. The L-shaped slot contains a spring and a spring block. Extension plates are slidably mounted in the handle boxes on both sides of the pot body via sliding grooves and sliders. A spring and a stop block are fitted inside the long grooves of the extension plates, and the stop block and spring block are compatible. Under normal conditions, the stop block abuts against the spring block. The abutment grooves on both sides of the locking ring provide movement space for the stop block. When the extension plate is stretched outwards, the stop block moves with the extension plate and loses its abutment against the spring block. When in use, spring two presses against the spring block, and the spring block firmly abuts against L-shaped locking block one, realizing reliable locking of the lid when the pot moves, effectively preventing the lid from shifting and slipping during the movement of the pot, eliminating secondary burns caused by the leakage of high-temperature food inside the pot, and improving connection stability; when it is necessary to open or close the lid, first use the handle to rotate the lid to release L-shaped locking block one from L-shaped locking groove one, and then retract the extension plate inward to make the abutment block and spring block re-abut and reset. The operation is smooth and convenient and the locking structure has strong adaptability.
[0018] The display screen on the front surface of the pot can show the pressure changes inside the pot in real time, allowing users to intuitively control the cooking process and accurately adjust parameters. This improves the safety, ease of operation, and reliability of the household pressure cooker, balancing efficiency and practicality to meet the core needs of safe daily cooking in the home.

[0029] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Example
[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a household pressure cooker with a pressure visualization indicator is provided, including a pot body 1. A locking ring 2 is fixedly installed on the upper surface of the pot body 1. The upper surface of the locking ring 2 has multiple L-shaped slots 3. A lid 4 is provided on the upper surface of the locking ring 2. Multiple L-shaped blocks 5 are fixedly installed on the lower surface of the lid 4. The L-shaped blocks 5 engage with the L-shaped slots 3. A through-type venting groove 6 is provided on the upper surface of the lid 4. L-shaped slots 7 are located on both sides of the venting groove 6. A water collection box 8 is provided on the upper surface of the lid 4. L-shaped blocks 9 are fixedly installed on the lower surface of the water collection box 8. The L-shaped blocks 9 engage with the L-shaped slots 7. A filter screen 10 is fixedly installed inside the venting groove 6. An air outlet hood 11 is fixedly installed on the upper surface of the air tank 6. An air pressure plug 12 is slidably installed inside the air outlet hood 11. A touch plate 13 is fixedly installed on the upper surface of the air pressure plug 12. Multiple mounting ring blocks 14 are fixedly installed on the upper surface of the water collection box 8. A condenser plate 15 is fixedly installed inside the mounting ring block 14. A rotating column 16 is rotatably installed between two adjacent mounting ring blocks 14 via a rotating shaft. A shaped striking block 17 is fixedly installed on the outer wall of the rotating column 16. The lower end of the shaped striking block 17 is located inside the air outlet hood 11 and above the touch plate 13. The upper end of the shaped striking block 17 is located above the condenser plate 15. A spring 18 is fixedly installed on the shaped striking block 17 and the mounting ring block 14 on the outer wall of the rotating column 16.
[0032] An operation screen 29 is provided on the front surface of the pot body 1;
[0033] The filter screen 10 fixed in the air outlet groove 6 on the cover 4 can effectively filter and divert the high-pressure gas discharged from the pot, avoiding airflow turbulence. The air outlet cover 11 on the upper surface of the air outlet groove 6 can accurately directionally constrain the high-pressure airflow during the heating, pressure holding and pressure relief stages, completely eliminating the problem of irregular airflow diffusion in all directions. The water collection box 8 of the cover 4, which is engaged with the L-shaped slot 2 7 and the L-shaped block 2 9, can collect high-temperature steam. The steam is quickly cooled by the condenser plate 15 in the mounting ring block 14, turning the hot air into cold air and discharging it, effectively preventing the operator from being scalded by high-temperature steam. The water droplets generated by condensation are directly collected in the water collection box 8, avoiding dripping and contaminating the work surface and eliminating the need for additional cleaning.
[0034] As the pressure inside the vent 11 increases, the pressure plug 12 slides upward, causing the upper surface contact plate 13 to strike the lower end of the irregularly shaped striking block 17. This causes the irregularly shaped striking block 17 to rotate around the axis, and its upper end strikes the condensing plate 15 simultaneously. In conjunction with the reset action of the spring 18 on the outside of the rotating column 16, the reciprocating striking is achieved, which promptly shakes off the water droplets attached to the surface of the condensing plate 15, solves the problem of water droplets clogging the vent holes of the condensing plate 15 after long-term use, ensures that the pressure relief channel is unobstructed, and avoids the safety hazard of abnormal pressure rise inside the pot.
[0035] The control screen 29 on the front surface of the pot body 1 provides visual pressure feedback, allowing operators to accurately view real-time pressure changes and easily adjust cooking parameters, thus enhancing the professionalism and convenience of cooking. The locking ring 2 and the lid 4 are connected by an L-shaped slot 3 and an L-shaped block 5, making disassembly and assembly convenient and the connection stable. The lid 4 and the water collection box 8 both adopt a modular snap-fit design, which can be quickly disassembled and assembled, facilitating daily cleaning and parts maintenance and replacement, reducing usage and maintenance costs, and adapting to high-frequency household use scenarios.
[0036] like Figure 1 , Figure 3 , Figure 8 and Figure 9 As shown, handle boxes 19 are fixedly installed on both sides of the pot body 1. Slide grooves 20 are opened on both sides of the inside of the handle boxes 19, and sliders 21 are slidably installed inside the two slide grooves 20.
[0037] An extension plate 22 is fixedly installed on the opposite sides of the two sliders 21;
[0038] The extension plate 22 has an elongated groove 23 inside, and a stop block 24 is slidably installed inside the elongated groove 23. A spring 28 is fixedly installed between the elongated groove 23 and the stop block 24.
[0039] Both sides of the locking ring 2 are provided with abutment grooves 25, which are connected to the L-shaped slot 3;
[0040] A spring 26 is fixedly installed inside the L-shaped slot 3. A spring block 27 is fixedly installed at the rear end of the spring 26. The spring block 27 is in contact with the L-shaped slot 5.
[0041] A handle 30 is fixedly installed on the upper surface of the cover 4;
[0042] The handle boxes 19 fixed on both sides of the pot body 1, together with the internal sliding grooves 20 and sliders 21, enable the smooth extension and retraction adjustment of the extension plate 22, avoiding accidental burns caused by the hands touching the hot pot body 1 when holding the pot body 1, and improving the safety and comfort of holding. The long groove 23, spring 28 and stop block 24 inside the extension plate 22 can be used to stabilize and limit the extension and retraction position of the extension plate 22, preventing it from retracting randomly during use.
[0043] The abutment grooves 25 on both sides of the locking ring 2 provide moving space for the abutment block 24, and the abutment block 24 is compatible with the spring block 27 connected to the spring 26 in the L-shaped slot 3. Under normal conditions, the abutment block 24 and the spring block 27 are in contact. When the extension plate 22 is pulled out, the abutment block 24 moves synchronously and releases the contact with the spring block 27. The spring 26 presses the spring block 27 to make the spring block 27 firmly abut against the L-shaped slot 5, so that the lid 4 is reliably locked when the pot body 1 moves, effectively preventing the lid 4 from shifting and slipping, eliminating secondary burns caused by the leakage of high-temperature food in the pot, and improving connection stability. When opening and closing the lid 4, the L-shaped slot 5 can be released from the L-shaped slot 3 by rotating the lid 4 through the handle 30 on the lid 4. Then, the extension plate 22 is retracted inward, and the abutment block 24 and the spring block 27 re-abut and reset. The operation is smooth and convenient, and it meets the needs of daily household use.
[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
